Though I've never tried it, I guess coffee just doesn't taste as good coming out of an aluminum bag. That's the only reason I can think of for inventing this astronaut coffee cup.

The On-Orbit Coffee Cup uses surface tension to hold liquid in zero-g. It was invented by astronaut Donald Pettit after what we can only imagine to be a particularly infuriatingly cup-o-joe-less space mission—STS-126.

The renders are by graphic artist Travis Baldwin and not of a real product since, obviously, the market for people who want to drink out of coffee cups in space is somewhat small. [Tuvie via Dvice]
